I still need to see your work to diagnose the issue, especially the soldering.

The backlight should indeed turn off when the robot is off.

Please post a photo of your wiring, you may have connected the backlight to the wrong place.

GND to 21, 22, 23 and 24
VDD to 17, 18, 19 and 20

Everything else should be OK!

Hi Vit, I lifted the new LCD from it's backlight using only my finger nails, starting in a corner. The backlight panel is slightly flexible which makes it easier to separate the two. Just be patient and very gentle! Try to keep the two adhesive strips on the backlight so that the LCD can be stuck st...

Yes, see here for the connections:

Mine is still going strong! LCD.jpg It is the LCD itself that fails. The caps and resistor I added to my DIY interface board only replicate the circuit on the PCB to reduce the number of wires. The replacement LCD I used probably isn't the greatest quality (look at the two corners on the right) but ...

I use this method, a normal high performance filter with a ladies foot sock as a pre-filter:

It does the same thing as the ultra filter but is much easier to clean!

Well done for finding another source! Looks like they are identical to the EastRising ones I found (they probably ARE EastRising), but cost $19.99 each instead of $5.88!

Have you connected OSC1 to VDD? Your diagram shows it disconnected!

Non-polarised.

I've had some requests to list the SMT component values used on my board, so here they are!
The value of the original resistor was 330 Ohms but 1K works fine.

NOTE: in a previous post asedovski has mentioned that if you connect the lcd (with neato off-battery removed) you have to press the buttons in specific sequence in order to initialise lcd - is it right? No, his comment was about having the Neato switched ON while performing the work. I do not recom...

That connection diagram drawn by oxdbxo would only work if the LCD contacts were facing upwards. Read my comment in the second post after his...

It sounds much more plausible that the Neato just hasn't "seen" the dock. It is merely returning to its starting position, which is just in front of where the dock is. Just starting from the dock isn't enough, it has to see it to get a proper fix on it. Bright sunlight can "dazzle&quo...

Get a multimeter and check that there are no short circuits between any of your wires. It looks like there may be a short here, circled in red...
Be sure to remove all solder spikes and splatters.

I think it's a bug in Neato Control. My workaround on V3.3: 1. Tick "Brush" - the main brush will start, speed is irrelevant. 2. Tick "Side Brush" - the main brush will stop and the side brush will start. 3. Untick "Brush" - should be no change in motor operation. 4. Un...

I'm also happy to report that the repair is holding up well. I've run several cleaning cycles from the dock and not one issue. Diagnostic readings are all as expected.

Hi Brian, I suppose that if you could identify the flash chip and hook it up to a suitable reader then you might have a slim chance, but there's no guarantee it would work. Personally, I wouldn't want to risk it. Unfortunately, I don't think any user upgradeable firmware updates have ever been relea...

You'll have to post some close up photos of your work, not much I can say otherwise apart from go back to square one and check everything. Closely.

I ordered some new chips from Mouser a few days ago and they were waiting for me when I got home today. I spent the evening fitting one and I'm pleased to report that this D85 is now a runner! :) U4 Replaced.JPG Ok, it's a bit of a mess but it's the first time I've attempted hot air rework at home w...
